Abstract
Abstract Apparatus for simultaneous reproduction of audible and visible information employs a rotary disk having several concentric tracks of recorded visible information and several concentric helical sound grooves or a single helical sound groove with several sound sequences super-imposed upon each other in accordance with the carrier frequency method. The sound reproducing system has one or more sound heads which are movable axially and radially of the disk into register with the outer ends of selected sound grooves or into register with the outer end of the single sound groove. The image reproducing system has one or more heads movable axially and radially of the disk into register with selected tracks. Each such track may consist of a helical groove which can be scanned to reproduce a series of images or an endless groove which can be scanned to reproduce a still image. The endless groove may comprise portions of different optical density, and each head of the image reproducing system then employs a light source which can be trained upon a selected endless groove to emit a light beam which is modified by portions of the scanned endless groove prior to impinging on a photoelectrcic transducer.
